MORGAN CHITTENDEN, OF DANBURY, CONNECTICUT.

SASH-FASTENER.

Specification of Letters Patent No. 25,487, dated September 20, 1859i.

To all whom t may concern:

Be it known that I, MORGAN CHITTENDEN, of Danbury, in the county ofFairfield and State of Connecticut, have invented anew and usefulSelf-Acting Sash-Fastener; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the accompanying drawings andlet-ters marked thereon and making part of this specification.

Figure l is a perspective view.

Fig. 2 is a horizontal view.

Fig. 3 is a longitudinal section. Fig. l is a longitudinal elevation.Figs. 5 and 6 are front views of the shank of the T shape wedge, whichis secured to the face of the meeting rail byscrews, i.

A are sectional parts of the meeting rails of the sash.

B is the case or front part of the fastener.

C is a plate or flange by which the wedge shank C is secured to theupper edge of the n'ieeting rail of the upper sash by screws, z'. Saidshank is secured by screws, z' to the face side of the meeting rail ofthe upper sash. Upon the upper end of the said shank and connected withthe plate C is formed what may be called a four sided, or conical Tshaped wedge, (the face side however being but slightly wedging) whichboth brings the upper and lower sash together, and takes up the sideplay of the sash. Said T shape wedge, or inclined planes, is itted tothe opening in the case B, which opening is formed partially of a shapecorresponding to that of the T shape wedge, or incline planes, in Fig.3.

o is a slide bolt or a spring catch in the case B made similar to thecommon cupboard catch, the tace side of the T shaped wedge (next to andagainst which the bevel end of the bolt o works) is provided with asocket (l. The upper end of the wedge and the end of the bolt arecorrespondingly beveled, so that as the T shaped wedge enters theopening in the case B, the bolt o will enter the socket CZ and thesashes will have been brought closely together and in uniformity withcach other. Now by pulling back the bolt o, by the hand or by means ofthe cord D, the sashes will be free to be raised or lowered, and byraising the upper sash, or lowering the lower sash to their places, thetwo sashes, the upper and lower are brought to their uniform position,and closely secured together in the manner as herein described.

The advantage claimed to be derived by this improvement is a moresubstantial useful and durable article for use and trade.

I do not claim a match plate mort-ised to receive a wedge catch, or backpost of the fastener as in patentof Dec. 19/54 No. 12,100wbut lVhat Iclaim and desire to secure by Letters Patent is The combination of a Tshaped wedge C with a bolt case B having an opening correspondingthereto-whereby the two sashes are uniformly and closely securedtogether substantially in the manner as and for the purpose described.

MORGAN CHITTENDEN.
